Federal Aviation Administration October 20, 2015 – Federal Register Recent Federal Regulation Documents

Proposed Amendment of Air Traffic Service (ATS) Routes; Southwest Oklahoma
Document Number: 2015-26498
Type: Proposed Rule
Date: 2015-10-20
Agency: Federal Aviation Administration, Department of Transportation
This action proposes to modify 3 VHF Omnidirectional Range (VOR) Federal airways (V-140, V-272, and V-440) in the vicinity of Sayre, OK. The FAA is proposing this action due to the scheduled decommissioning of the Sayre, OK (SYO), VOR/Tactical Air Navigation (VORTAC) facility that provides navigation guidance for a portion of the airways listed. This action would enhance the route structure within the National Airspace System.
Amendment of Class D Airspace and Revocation of Class E Airspace; Columbus, Ohio State University Airport, OH, and Amendment of Class E Airspace; Columbus, OH
Document Number: 2015-26280
Type: Rule
Date: 2015-10-20
Agency: Federal Aviation Administration, Department of Transportation
This action amends Class D and Class E airspace and removes Class E airspace in the Columbus, OH, area. Decommissioning of the non- directional radio beacon (NDB) and/or cancellation of NDB approaches at Ohio State University Airport, Columbus, OH, has made this action necessary for the safety and management of Instrument Flight Rules (IFR) operations at the airport. Also, the geographic coordinates of the airport, as well as the Port Columbus International Airport, are updated.
Establishment of Class E Airspace; Wakeeney, KS
Document Number: 2015-26276
Type: Rule
Date: 2015-10-20
Agency: Federal Aviation Administration, Department of Transportation
This action establishes Class E airspace at Wakeeney, KS. Controlled airspace is necessary to accommodate new Standard Instrument Approach Procedures (SIAPs) at Trego Wakeeney Airport. The FAA is taking this action to enhance the safety and management of Instrument Flight Rules (IFR) operations at the airport. The airport name also is correctly noted in the airspace description.
Airworthiness Directives; Bombardier, Inc. Airplanes
Document Number: 2015-26218
Type: Rule
Date: 2015-10-20
Agency: Federal Aviation Administration, Department of Transportation
We are adopting a new airworthiness directive (AD) for certain Bombardier, Inc. Model DHC-8-102, -103, -106, -201, -202, -301, -311, and -315 airplanes. This AD was prompted by reports of un-annunciated failures of the direct current (DC) starter generator, which caused caution indicators of the affected systems to illuminate and prompted emergency descents and landings. This AD requires replacing the DC generator control units (GCUs) with new GCUs and replacing the GCU label. We are issuing this AD to prevent a low voltage condition on the left main DC bus, which, during critical phases of flight, could result in the loss of flight management, navigation, and transponder systems, and could affect continued safe flight.
Airworthiness Directives; Various Sikorsky-Manufactured Transport and Restricted Category Helicopters
Document Number: 2015-25976
Type: Rule
Date: 2015-10-20
Agency: Federal Aviation Administration, Department of Transportation
We are superseding Airworthiness Directive (AD) 98-26-02 for certain Sikorsky Aircraft Corporation (Sikorsky) Model S-61A, D, E, L, N, NM, R, and V helicopters. AD 98-26-02 required determining whether the main rotor shaft (MRS) was used in repetitive external lift (REL) operations, performing a nondestructive inspection (NDI) for cracks, replacing any unairworthy MRS, and establishing retirement lives for each REL MRS. This new AD retains some of the requirements of AD 98-26- 02 but determines a new retirement life for each MRS, expands the applicability to include additional helicopters, and requires removing from service any MRS with oversized dowel pin bores. This AD was prompted by the manufacturer's reevaluation of the retirement life for the MRS based on torque, ground-air-ground (GAG) cycle, and fatigue testing. We are issuing this AD to prevent MRS structural failure, loss of power to the main rotor, and subsequent loss of control of the helicopter.
